At this time, both the inner and outer doors are locked. After the fan stops working, the buzzer sounds The inner door can be opened with a sound, the personnel or goods exit the air shower room, the inner door is closed, and the whole process is over.

2) Exit from the clean area When the inner door is opened, the outer door is automatically locked, personnel or goods enter the air shower room, the inner door is closed, the personnel or goods pass through the infrared probe and the outer door can be opened with a buzzer, the personnel or goods exit the air shower room, and the outer door is closed. The whole process is over.

3) The fan of the air shower room must have the function of automatic time adjustment.

4) Automatic protection function of air shower room When there is a door in the air shower room or the door machine fails to close, the system automatically exits the interlock function after a certain period of time, and the system automatically resumes the interlock function after the two doors are closed.

16.2 Requirements for the control of the air shower room at the gate of the workshop

1) Enter from non-clean area When the outer door is opened, the inner door is automatically locked.
